Abstract: A fastening device for connecting a rope to an object includes a shank which contains an aperture through which the rope loops, and in addition a hook at one end of the shank. The hook carries a keeper which pivots on it between closed and open positions, and is urged to its closed position by a coil-type compression spring which encircles the shank. The spring creates rope channels along the sides of the shank, and these channels confine the rope so as to maintain the loop at the aperture. However, the spring may be compressed to expose the aperture so that the rope may be maneuvered through it.
